چکیده
در این پژوهش ریزساختار، توزیع عناصر و فازها و مقاومت به خوردگی آلیاژ Ti-10Mo ساخته شده به روش تف جوشی قوس پلاسما (SPS ) مورد بررسی قرار گرفت. برای ساخت آلیاژ Ti-10Mo به روش تف جوشی قوس پلاسما مقدار 90 درصد وزنی پودر تیتانیم با 10 درصد وزنی پودر مولیبدن در آسیای گلوله‌ای به مدت 10 ساعت با نسبت گلوله به پودر برابر 1 به 10 مخلوط شدند. نمونه‌های مخلوط پودری در دمای 1250 درجه سانتیگراد تحت فشار 50 مگا پاسکال، تحت خلاء 1/0 پاسکال و به مدت 6 دقیقه به روش قوس پلاسما ساخته شدند. ریزساختار این آلیاژ شامل فاز بتا و ساختار آلفا/بتا است که در مرزدانه‌های آن، دانه‌های سوزنی آلفا رشد کرده است. از بررسی‌های مربوط به پتانسیل مدارباز چنین استدلال می‌شود که یک لایه اکسید محافظ روی آلیاژ در معرض اکسیژن تشکیل می‌شود و با توجه به منطقه گسترده پسیو که روی منحنی پلاریزاسیون قابل مشاهده است نرخ خوردگی آلیاژ عمدتا توسط این لایه کنترل می‌شود. بررسی‌های مربوط به نمودارهای امپدانس الکتروشیمیایی نشان می‌دهند که لایه پسیو تشکیل شده بر روی آلیاژ دارای دو ثابت زمانی بوده و نتیجه‌گیری می‌شود که از یک لایه مانع داخلی و یک لایه متخلخل بیرونی تشکیل شده است که لایه مانع داخلی، مقاومت به خوردگی خوبی را برای آلیاژ تضمین می‌کند.

چکیده English

In this research, the microstructure, distribution of elements and constituent phases, of SPSed Ti-10Mo alloy were evaluated and their effect on its corrosion resistance were investigated. To prepare Ti-10Mo alloy by spark plasma sintering, 90 wt.% of powder titanium was mixed with 10 wt.% of molybdenum powder in a ball mill for 10 hours. The ratio of ball to powder were 1:10. The powder mixture were sintered at 1250˚C at pressure of 50 MPa for 6 min in a vacuum of 0.1 Pa. In the microstructure β phase and α/β structure, in which acicular α phase have grown in the grain boundaries, are seen. Analysis of open circuit potential indicated that a passive film formed spontaneously on the alloy, and due the wide passive region that can be seen on the polarization curve, would another evidence to formation of the passive film. The EIS results also confirm that the passive oxide film formed on the alloy is a bi-layer structure consisted of an outer porous layer and an inner barrier layer, in which the inner barrier layer ensures the alloy a good corrosion resistance.
